Abstract (en)

[origin: US2014120558A1] In some cases, the described systems and methods include obtaining a cell sample containing multiple antibody-producing cells. In such cases, the cells can be tagged with a cross-linking reagent having a first portion configured to bind to a marker on the antibody-producing cells and a second portion configured to bind to an antigen of interest. In some instances, the tagged antibody-producing cells are exposed to the antigen of interest such that the antigen becomes bound to the cells. In some such instances, the antibody-producing cells are also allowed to produce an antibody, such that a portion of the antibody-producing cells produce an antigen-specific antibody that binds to the antigen of interest. To identify cells that produce the antigen-specific antibody, the tagged cells can be exposed to a labeled secondary antibody that is configured to bind to the antigen-specific antibody. Other implementations are also described.
